What else can I help you with?
Unlike in an ideal gas in a real gas A. all particles move in the same direction B. all particles have the same kinetic energy C. the particles cannot diffuse D. particles exert attractive forces?
D. Particles exert attractive forces. In real gases, the particles do not always move in the same direction, have the same kinetic energy, or have difficulty diffusing due to interactions between the particles leading to attractive forces that are not present in ideal gases.
What effect does the speed of molecules have of matter?
The speed of molecules affects the temperature of a substance. As the speed of molecules increases, the temperature of the substance also increases. This can lead to changes in the physical state of matter, such as melting or boiling.
What describes the properties of solids liquids and gases in terms of the motion of particles?
Solid - Particles vibrate and rotate about a fixed position and do not diffuse measurably Liquid - Particles move freely in all directions slowly and diffuse slowly Gas - Particles move freely in all directions rapidly and diffuse rapidly
In what state the atoms move the fastest?
Particles in the gaseous state move at a very high rate and have a large effect on each other. Particles on a liquid state move slower but still have a measurable effect on each other. Particles in a solid state move very slowly and have little effect on each other.
Which subatomic particle move the fastest?
Yes, particles in a liquid do move faster than particles in a solid.Here is a list from slowest moving particles to fastest:solids (compact particles with little movement: vibrations.)liquids (lightly compact particles, which move around freely over one another.)gasses (particles are not compact and spread evenly apart as far as possible.)plasma (particle much like gas, more extreme. Plasma particles only occur at very high temperatures.)
Why doesn't a gas particle move at the same speed as all temperatures?
Gas particles move at different speeds due to their kinetic energy, which is related to the temperature of the gas. At higher temperatures, gas particles have more kinetic energy and move faster on average, leading to a range of speeds rather than all particles moving at the same speed. This distribution of speeds is described by the Maxwell-Boltzmann distribution.
Why do all gases with the same average kinetic energy move at the same velocity?
Gases with the same average kinetic energy move at the same velocity because kinetic energy is directly related to the speed of gas particles. When gases have the same average kinetic energy, it means they have the same amount of energy to move, resulting in them moving at the same speed.
Do larger particles move faster than smaller ones?
because they have a larger mass and require a greater energy to move at the same speed. KE=1/2mv2 where m is mass, v is velocity and KE is kinetic energy so for the same energy if the mass is doubled then v2 is halved, resulting in a slower speed
Is that true that the more energy of a photon the bigger the mass it possesses?
No, all photons have the same mass. Photons are massless (i.e. zero). All the energy in a photon is in its momentum, but increasing its momentum does not change it speed which is always "the speed of light". All massless particles always move at the speed of light.
What 3 ways do particles in gas move?
Particles in gas move in a straight line until they collide with another particle or the walls of the container. They move at a constant speed until they collide, then change direction. The particles have random motion, moving in all directions.
Unlike in an ideal gas in a real gas A. all particles move in the same direction B. all particles have the same kinetic energy C. the particles cannot diffuse D. particles exert attractive forces?
D. Particles exert attractive forces. In real gases, the particles do not always move in the same direction, have the same kinetic energy, or have difficulty diffusing due to interactions between the particles leading to attractive forces that are not present in ideal gases.
Why is it useful to find the average speed of a object?
Most things don't move with the same speed at all times
What are the six important points to particle theory of matter?
1.All matter is made up of particles. 2.All particles have spaces between them. 3.Particles are always in motion. 4.Particles have attraction forces. 5.Temperature effects the speed in which particles move. 6.All particles of one substance are identical
Do particles in sold ice move slower than particles in liquid water?
Yes. The colder the substance become, the slower the particles move. Actually in pure ice the particles do not move at all.
When an object increases in temperature do the particles speed up or slow down?
They speed up. Heat is actually molecular motion. Absolute zero (−459.67°F) is the temperature where the particles have no motion at all.
Do all galaxies move at the same speed?
As with all space questions about speed, it all depends on your point of reference. Within the Milky Way, the orbital rate of the stars increase as you move away from the centre of the galaxy.
Which diffuse faster heavy particles or light particles?
In general lighter particles should diffuse faster than heavier particles, this could be extrapolated from the relationship to mass, volume, and energy. If we look at particles of all the same, ideal, substance, we would see that an object with less mass would be smaller but would also require less energy to move. That is, at the same temperature a particle of lower mass would move faster than a similar particle of heavier mass. We also see that smaller particles also maximize surface area/mass - this is also conducive to faster diffusion.
